Abstract:
A printhead carrier having a zero clearance bearing arrangement includes a first open-faced bearing coupled to a dampener frame. The first open-faced bearing has a first bearing surface positioned to contact the cylindrical guide surface of a guide rod of an imaging apparatus. A second open-faced bearing is coupled to the dampener frame. The second open-faced bearing has a second bearing surface positioned to contact the cylindrical guide surface of the guide rod. The guide rod is diametrically positioned between the first open-faced bearing and the second open-faced bearing. An elastic foam member is interposed between the first open-faced bearing and the dampener frame. The elastic foam member is compressed to exert an expansion force between the first open-faced bearing and the dampener frame to load the second open-faced bearing on the guide rod in a zero-clearance relationship with the guide rod.
